Fox Knives' reinterpretation of the famous Billao knife is a tribute to the traditional knife of the official equipment of the Italian Africa Police (PAI). Fox Knives wanted to maintain the historical coherence and authentic aesthetics of the original knife while making improvements to provide sturdiness thanks to new production technologies.

The traditional Billao knife, like the one from Fox Knives, features a leaf blade and a three-pointed pommel, with the central point being the protrusion of the blade's tang. The handle is made of buffalo horn, a traditional material that adds authenticity to the design. The sheath is made of leather and has loops and strings that allow it to be attached to the hips. It has been specially designed to accommodate both the handle and the hilt, maintaining the practicality and originality of the Billao knife.
In addition to the attention to aesthetics, Fox Knives has worked to guarantee solidity to the reinterpreted knife: the satin-finished N690Co blade and the handle are of high quality and resistant to daily stress. This combination of historical authenticity and modern durability makes the Fox Knives Billao an item enjoyed by knife enthusiasts and history lovers alike.
